The phone is sending random messages and typing on its own.

You can clear the cache in the messages. Don't do the storage. And also, clear storage and Gboard. We have to see if it happens.

In messages, I just do the storage, clear storage? No, do cache. Remember that we got a few things deleted after doing that. We don't want to do that anymore.

On the Gboard, you have to do the storage.

If it's pressing random buttons, then it's usually not the show. It's the keyboard.

We have to fix it. And it's not easy, so I'm not quite sure if you will be able to do it.
